Change ARM PKHTB and PKHBT instructions to use a shift_imm operand to avoid
...
printing "lsl #0 ". This fixes the remaining parts of pr7792. Make
corresponding changes for encoding/decoding these instructions.

Generalize a pattern for PKHTB: an SRL of 16-31 bits will guarantee
...
that the high halfword is zero. The shift need not be exactly 16 bits.
